The housekeeper and the professor by Yoko Ogawa, translated by Stephen Snyder A novel translated from the Japanese, where nothing much happens and prime numbers play a central role, may not sound like the most relaxing summer read.

Imagine a biologist trying to deduce the life cycle of an unknown creature by observing it just long enough to witness four beats of its heart. Nowadays, we know the Sun follows an eleven-year cycle, so even lifelong professional astronomers are likely to witness no more than four of its pulsations. Solar astronomy is truly a multigenerational science and its beginnings are brilliantly summarised in Stuart Clark's story, built around the greatest magnetic storm ever recorded.

If the quest for a physical theory of everything, and some of the strange concepts that have sprung from it, strikes you as somewhat mystical, then this is just the book you need to explore the idea further.

When Number story first landed on my desk I was struck by its prettiness. With its tasteful and slightly old-fashioned cover design, the unusually compact format for a hardback, and the unassuming title, this book clearly isn't desperate for attention. So I was intrigued to find out whether this quiet confidence is justified by its content, and I'm glad to report that it is.
